I'm not sure here that I will be able to track somehow that different terms
were matched to the same document...
I'm thinking more about little another way: when query scores some document
- save the query term for that document somewhere. Probably it would be
some map in some class SearchContext. I could write something like this:
SearchContext sc = getSearchContext(); // - does such
search context exist in Lucene? Maybe QueryContext
sc.getDocTerms().get(docID).add(query.getTerm())); // docTerms here is a
Map<Int, List<String>> - where the key - is a document ID and the value -
is a list of terms by whom this document was matched.
I need to save somewhere the document ID and the term matched that
document. Could somebody advise me an appropriate place?
